The recent years have witnessed a considerable rise in the number of vehicles, which has placed transportation infrastructure and traffic control under tremendous pressure. Yielding timely accurate flow information is essential development strategies. Despite continual advances wealth literature available intelligent system (ITS), there lack practical counting system, readily deployable on edge...

There have been research initiatives in centralized control recently, which advocate that the control of an autonomous system (AS) should be performed in a centralized fashion. In this paper, we propose an approach to perform traffic engineering and routing in networks with centralized control, named LP-redirect. LP-redirect is based on an efficient formulation of linear programming (LP) that r...

This paper considers the traffic engineering of MPLS-based virtual private networks (VPNs) with multiple classes of service. We focus on two main issues. Firstly, we point out that the one LSP per ingress-egress pair constraint can be relaxed for the case of MPLS-based VPNs due to the ease in classifying flows on a per-VPN basis. This allows us to use LSP with finer granularity and thus better ...

Slow and suspicious malicious activities on modern computer networks are increasingly hard to detect. An attacker may take days, weeks or months to complete an attack life cycle. A particular challenge is to monitor for stealthy attempts deliberately designed to stay beneath detection thresholds. This doctoral research presents a theoretical framework for effective monitoring of such activities...

Intelligent Driver Model (IDM) is a well-known microscopic model of traffic flow within the traffic engineering societies. While it is a powerful technique for modeling traffic flows, the Intelligent Driver Model lacks the potential of accommodating the notion of drivers’ heterogeneous behavior whenever they are on roads. Concerning the above mentioned, this paper takes the lane to recognize th...

This paper specifies a procedure to derive trafSic volume information for distribution of objectoriented applications. An accurate picture of trafSic volumes between application components and sites, and among application components is crucial for eflective design of any distributed application. The procedure represents a considerable improvement over the traditional practice of requiring appli...

The aim of this article is to explore the linkage of two microsimulators developed at the University College London. At present, these models deal independently with buses at either bus stops or traffic networks. First, both microsimulators are described in some detail. The generic way in which both models can be connected is then proposed. As a result of this analysis, the main issues for a co...

This thesis deals with the fully automatic generation of semantic annotations for medical imaging data by means of medical image segmentation and labeling. In particular, we focus on the segmentation of the human brain and related structures from magnetic resonance imaging (MRI) data. We present three novel probabilistic methods from the field of database-guided knowledge-based medical image se...
